HENRY G. BROOKS, OF MARSHALL, MICHIGAN.

WATER-GAG E.

SPECIFICATION forming part of Letters Patent No. 734,040, dated July 21,1903.

Application filed March 7, 1903.

To all whom it may concern.-

Be it known that I, HENRY G. BROOKS, a citizen of the United States,residing at Marshall, in the county of Calhoun and State of Michigan,have invented certain new and useful Improvements in Water-Gages; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being bad to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

My invention relates'to improvements in water-gages; and the objects ofmy improvements are, first, to provide a seating adapted to the fixturesnow in common use; second, to provide a gage for vertical adjustment, sothat one end of the glass will not be too far entered and the other notfar enough, and, third, to provide a lining for the glass tube whichalso forms a raceway for the water and steam and also a background forthe waterlevel.

Figure 2 is a vertical view of a water-gage,

partly in section, in which my improvements. Fig. 1 is a sectional viewof my are shown. improved seating.

Similar letters and figures refer to similar parts in both views.

lindrical shell 2, having ashoulder 3 and theinner tube 1, extended toview beyond the packing-nut 7 to receive the end of the raceway 4. Theraceway 4:, Fig. 2, consists of a tube of less outer diameter 'than'theinner diameter of the glass and of the required length to enter theextended inner tube 1 of the seating both at the top and bottom. Thisraceway is provided with holes 5 and 5 near I attain these objects bythe mechan ism illustrated in the accompanying draw-- ings, inwhicherial No. 146,680. (No model.)

I the ends to permit the water and steam to enter the space between theraceway and the glass,'so as to maintain in said space thelevel of thewater in the boiler. The tube is bulged shoulder to support it, as shownat 6, Fig. 2. This raceway receives the wear incident to the motion ofthe water and steam and also forms a conduit for the sediment that mayenter it. p The construction of the shell-seating is the same for eitherend of the glass, except that one is about one-half the depth of theother. This difference of construction is of great advantage in placingthe glass in position, the glass being inserted first in the deeper oneand then brought to the bottom of the shallower. It will be noted thatthe glass is entered equally at each end, thus constituting a gage forsetting the glass. This shell-seating can be made in sizes to meet therequirements of fixtures now in use.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In combination with a glass gage-tube and fixtures, a pair of shellsfitted into said fixtures, receiving the ends of said glass tube andprovided with inner tubes 1 and shoulders 3, means for holding saidshoulders against said fixtures and a tubular raceway fitting at itsends into the tubes'l and arranged within the said glass' tube, the saidraceway being provided with openings discharging into the space withinthe latter substantially as set forth.

2. In combination with a tubular fixture, a

shell having an inner tube 1, means'for clamping said shell in saidfixture, a glass gagetube fitting detachably into said shell, and atubular raceway, fitting into said inner tube substantially as setforth. 3. In combination with a tubular fixture, a shell having an innertube 1 and an exterior annular shoulder 23, means engaging the saidshoulder to clamp the said shell in said fixture, a glass gage-tubefitting into the said shell and a tubular raceway fitting-into saidinner tube 1 substantially as set forth.

4. A raceway-tube, having holes in its sides near its ends and a bulgedpart or shoulder in proximity thereto at one end, in combinabetween theholes at the lower end to form av tion with tubular parts which receivethe said ends and on one of which the said shoulder that rests thereonand provided with openrests, a glass gage-tube exterior to said raceingsabove the same,-a glass gage-tube surway-tube and means for holding saidgagerounding the said raceway-tube, and means I 5 tube and tubular partsin place. for holding the said glass tube in place sub- 5 5.
